This is getting kind of expensive, I've replaced my t-cell 15 each year for the last three years (OEM not generic brand) and can't seem to keep the pool chlorinated. 35k gallon pool, chemical levels fine using a taylor R-2006 kit (but no salt level test), running the generator for a minimum of 12 hours a day at 95%, salt levels at 3300 (3200-3700 recommended). The only way to keep the chlorine levels in balance is to supplement with a gallon of bleach every few days. The original Tcell ran for 5 years with no issues, running at about 70% kept it at proper levels and shocking (100%) for 24 hours weekly worked perfectly. I've tested chlorine levels coming right off the generator and they're seemingly no different than the pool, (or perhaps the sensitivity of the test kit isn't precise enough to measure the variability??) It is connected to a jandy control system and neither the jandy display nor the panel on the generator itself are throwing any errors. No scaling on the unit itself. The one other issue I have which may be interfering?? is that the water leveler is fed from a well which has metals so I need to supplement somewhat frequently with Pool Magnet Plus by Bioguard (which works extremely well at getting the green tint back to blue).
1. what is the best way to test?
2. additional information I can provide? (I can provide the specific levels but I reacquaint myself with pool school each year so I'm fairly confident that CYA, PH, etc are all good.)
3. ideas/recommendations to resolve?
